fermi
Figuring out something quickly by just using estimates to the closest power of ten, because sometimes you just want to know if the thing you're doing is worth or is gonna cost ten bucks, a hundred, or a cool grand. Named after Fermi Estimation, a trick used by Enrico Fermi to wow his fellow nerds at parties by estimating shit without knowing 100% everything about the problem, sometimes without even writing shit down. You're not going to get exact numbers, but you're gonna get close enough. Most notably, dude estimated the power of a fucking nuclear bomb by just dropping papers as the bomb went off and measuring how far the shockwave moved that shit — and he was only off by a bit.
The Urban Dictionary Mug

The mug arrived very packed and on time. I love how well crafted the coffee mug is. I plan on ordering other merch from URBAN Dictionary soon. Thanks.
It morbed its way into my anus, a bit weird, but otherwise happy with my purchase
After watching that anal jar video, I felt inspired. That's when I found this mug.
FUCK YEAAAAAAAA! MUUUUGZ WOOOOOO
Happy with my purchase
amazing I will buy this. it will be my child. I WILL BE KING OF THE 0w0
I loved this mug! when i drink out of it it always has a horrible stench and honestly i dont mind because i love smelling it. my boyfriend thinks i should throw it away because he says "its has lead poisoning" but i cant get rid of it. when my mom died i bought her a mug that said "deceased" because i thought it would brighten the moment when i open presents at her funeral (it worked). but if your looking for something to buy, you should really get one of these mugs. they are cute, nerdy, and remind me of my dead mother!
Yay. I got a mug... And it has the most accurate definition of my name ever lmfao. The quality is great and it's totally worth the price. For me, at least :)
The accuracy is real! My husband and I have 3 daughters. Our last name is Staats, in UD was spot on! Unbelievable! I got it to my husband just in time for Father's Day! Lol!
love it sm, gives a clear understanding of the word every sip thankyou
I nutted in the mug. Loved it!!!!!!!!
I fucked this mug so hard, It became pregnant

Exactly as I ordered it. Shipping was perfect, got updates, accurate date of delivery, and no damage. This is a gift for my little brother.
i was put on a list for buying this mug. 10/10 would recommend
Great customer service and was a fun surprise for an inside joke to a coworker. 😊
Nice cup! Seems to be a quality piece.
This mug reminds me of when I was happy. When I was a wee little winker enjoying the wonders of this life!
The, "Wenomechainsama" Mug has amazing quality and an amazing definition! Can't belive my child's generation is so funny! Love - Sharen, 55, On facebook !<3
this mug reminds me of my cat, it does nothing and cant pour me a nice cup of joe. It is horrible, it doesn't tell nor does it allow me sip on it. It stops me from drinking from it, its like the mug is trying to torture me.
love this mug! Goes perfect with the Morbius meal.
